PPIB and infectious meningitis: Similar to a study by Carrillo-Ávila et al. that also compared culture to 2 NAATs that targeted the cfb and sip genes [18], we found high concordance of 95% between AllplexTM Meningitis-B PCR and the HG GBS LAMP assays, suggesting that the culture negative, HG GBS LAMP positive, AllplexTM-positive samples were true-positive samples.
